Notizen: Particle-precipitation-aided chemical vapor deposition (PP-CVD) is a modification of the conventional CVD process, where an aerosol is formed in the gas phase and particles are deposited on a substrate. The driving force for particle deposition is thermophoresis. The synthesis of titanium nitride (TiN) has been studied. TiN is formed on the substrate, as well as in the gas phase. At low temperature differences, only dense microstructures with equiaxed grains are observed; porous coherent layers are found in experiments where larger temperature differences are applied. Additional increase in the temperature difference only leads to loose powder deposits. In principle, the PP-CVD process is a suitable method for the synthesis of thin porous layers of ceramics.

Notizen: Abstract A deNOx catalyst was prepared by wash-coating a cobalt ion exchanged ZSM-5 zeolite together with an alumina binder on a cordierite honeycomb structure. A few types of the Co-ZSM-5 based catalysts were tested for NOx reduction with C2H4 under oxidizing conditions in the temperature range between 250–600°C. Preliminary tests of the catalytic activity of the systems showed NOx reduction up to 95% at temperatures between 400–550°C using a mixture of a synthetic gas and air as reactant.
